what we don't have, inspection records, job cards, we have from about 1933 going forward, plumbing permits and inspections from about 1976 going forward and electrical permits from about 1985 going forward so just as mr. corn field said if you find a tag or something on your circuit breaker box or something and it's old. with a straight edge or something take it off and save it. it may be the only record that something was done at that time. >> yeah, you had a question? >> you have permits for modifications. >> the question is do you make a request for documents and nothing turns up which happens frequently, maybe. where else would we look?
